If we provide an AccelGroup when creating a menu item using a sock ID,
it installs the GTK default accelerator, accelerator we can't remove
since we don't know about it. So, don't give an AccelGroup so GTK
don't install it's own accelerator.
This fix also required to properly update the accelerator on some item
we used to ignore since the update didn't work anyway (since the GTK
accelerator was displayed instead).
Note that this doesn't fix the fact the editor popup menu accelerators
are never updated after startup so they don't get updated before
restart after changing a keybinding in the preferences. This is a
separate (and less problematic) issue due to a simple lack of update.
Closes#1912683 and #3599251.
Previously was hard coded with options to suit xterm. As this is
being replaced with different terminal programs some do not accept
the same options. The new setting stores the whole command with
%c to substitute the script name. Upgrades old settings if a new
one does not exist.
This makes the "wordchars" setting from filetypes.common and each
specific filetype override filetype.common's "whitespace_chars"
setting, rather than it overriding filetype-specific "wordchars".
This makes the it easy to chose filetype-specific "wordchars", where
before user had not only to update this setting, but also the
filetype.common "whitespace_chars" setting if it listed one or more of
the new characters for the change to actually have an effect -- and
changing "whitespace_chars" for every filetype.
Closes#3429368.
Use the current document's directory unless the directory field has
already been edited and the current document has not changed.
Otherwise, prepend the current document's directory to the drop-down
history in case it is wanted.
This is useful to avoid losing the edited directory when it is less
likely the user wants to use the current document's directory.
With newer GTK+ releases, leaving this field blank causes the "Recent
Files" "feature" to be used rather the the expected current working
directory. No replacement text added to explain the new behaviour since
it would be incorrect with older GTK+ versions, would likely be incorrect
on Windows with native dialogs and it will possibly be reverted in GTK+
in the future.
