Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.
Problem: Saving/restoring search patterns share saved last_idx.
Solution: Use a separate saved last_idx for saving search patterns for
functions and incremental search.
Problem: Crash when last search pat is set but not last substitute pat.
Solution: Do not mix up last search pattern and last subtitute pattern.
(closes#3647)
Problem: Saved last search pattern may not be restored.
Solution: Call restore_last_search_pattern(). Add a check for balancing
saving and restoring the last search pattern.
Problem: Searchpair() might return an invalid value on timeout.
Solution: When the second search times out, do not accept a match from the
first search. (Daniel Hahler, closes#2552)
Problem: Slow redrawing with DirectX.
Solution: Avoid calling gui_mch_flush() unnecessarily, especially when
updating the cursor. (Ken Takata, closes#2560)
Problem: Cannot use a lambda for the skip argument to searchpair().
Solution: Evaluate a partial, funcref and lambda. (LemonBoy, closes#1454,
closes#2265)
Problem: Incremental search only shows one match.
Solution: When 'incsearch' and and 'hlsearch' are both set highlight all
matches. (haya14busa, closes#2198)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: ml_get error with :psearch in buffer without a name. (Dominique
Pelle)
Solution: Use the buffer number instead of the file name. Check the cursor
position.
Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: When 'wrapscan' is off "gn" does not select the whole pattern when
it's the last one in the text. (KeyboardFire)
Solution: Check if the search fails. (Christian Brabandt, closes#1683)
Problem: Using a text object to select quoted text fails when 'selection'
is set to "exclusive". (Guraga)
Solution: Swap cursor and visual start position. (Christian Brabandt,
closes#1687)
Problem: The ":stag" command does not respect 'switchbuf'.
Solution: Check 'switchbuf' for tag commands that may open a new window.
(Ingo Karkat, closes#1681) Define macros for the return values
of getfile().
Problem: The ";" command does not work after characters with a lower byte
that is NUL.
Solution: Properly check for not having a previous character. (Hirohito
Higashi)
Problem: Order of matches for 'omnifunc' is messed up. (Danny Su)
Solution: Do not set compl_curr_match when called from complete_check().
(closes#1168)
Problem: There is no equivalent of 'smartcase' for a tag search.
Solution: Add value "followscs" and "smart" to 'tagcase'. (Christian
Brabandt, closes#712) Turn tagcase test into new style.
Problem: "cgn" and "dgn" do not work correctly with a single character
match and the replacement includes the searched pattern. (John
Beckett)
Solution: If the match is found in the wrong column try in the next column.
Turn the test into new style. (Christian Brabandt)
