weechat::info_get( "weechat_dir", "" ) should return the absolute path without a trailing shlash.

If you start weechat for example:

  'weechat-curses --dir .weechat-test/'

weechat::info_get( "weechat_dir", "" ) will return:

  '.weechat-test/'

This can cause problems if i.e. a script uses

  weechat::info_get( "weechat_dir", "" )

to save a config-file in the 'weechat-dir' and save that
location with 'plugin_set_option' for late use.

If the cwd differs next time, starting weechat, say:

  'weechat-curses --dir ../.weechat-test/'

Now, the saved option will point to an not existing file.

In the worst case an other file with the same name, having that
'wrong' path, could be corrupted
