Problem: ":sign place" requires the buffer argument.
Solution: Make the argument optional. Also update the help and clean up the
sign test. (Yegappan Lakshmanan, closes#3767)
Problem: Deleting signs and completion for :sign is insufficient.
Solution: Add deleting signs in a specified or any group from the current
cursor location. Add group and priority to sign command
completion. Add tests for different sign unplace commands. Update
help text. Add tests for sign jump with group. Update help for
sign jump. (Yegappan Lakshmanan, closes#3731)
Problem: Using sign group names is inefficient.
Solution: Store group names in a hash table and use a reference to them.
Also remove unnecessary use of ":exe" from the tests. (Yegappan
Lakshmanan, closes#3715)
Problem: Placing signs can be complicated.
Solution: Add functions for defining and placing signs. Introduce a group
name to avoid different plugins using the same signs. (Yegappan
Lakshmanan, closes#3652)
Problem: Sign test fails on MS-Windows when using the distributed zip
archives.
Solution: Create dummy files instead of relying on files in the pixmaps
directory.
