The g_match_info_fetch_pos() function uses a signed value for the match_num
parameter, even though values less than 0 are not valid, so a cast is used.
Replacing spaces used for alignment with tabs would often break the
alignment as tab stop positions were not checked. It's also not
possible to distinguish between a true space and a single aligning
space, so we should ignore all spaces outside of indentation.
Although go to marker commands (or other keybindings) don't work, the
marker margin can still be useful, and improves alignment with the
original sci widget when using the Top & Bottom split.
There is still 3 signed values implicitly converted to unsigned not
fixed, but they aren't really legitimate and would require a behavior
change in some corner cases.
Most noteworthy change is that all build commands IDs and groups are
now unsigned everywhere negative values aren't explicitly handled with
a special meaning. This should not change anything in behavior, only
makes clear the index won't underflow.
These actions were marked as document sensitive but their sensitivity
is already managed by the navqueue, so making them document sensitive
only leads to them being wrongly updated when the document count
changes from or to 0.
So, make them initially insensitive and let the navqueue correctly
handle their later sensitiveness.
This seems required for GtkBuilder to be able to connect signals. However, this change may break Windows
builds. Needs to be tested and worked around if it is the case.
Having C language snippets as global is wrong, moved them to several
language positions. This files low rate of change and lack of ML
interest in putting language specific snippets in it suggests that
it isn't worth fixing the repitition or moving snippets to filetype
files.
Add filetype_get_comment_open_close() to get appropriate start and end
comment markers from a filetype, and use it everywhere these markers
are fetched.
This fixes a crash in editor_insert_multiline_comment() if only single
comments are available (closes#3449635).
Although this doesn't change anything in practice, it started to be a
nightmare trying to deal with compilers warnings about "missing"
initializers, which are generally good but not in that file.
