3e29793d04 improve detection of msgs to be translated
This change does several things. First, it works around a quirk of the
`xgetttext` command that only recognizes description strings in even
numbered position on the command. Second, it allows descriptions
introduced by the `-d` short flag to be recognized.

More importantly, it normalizes the strings so that `xgettext` correctly
extracts them into the *.po file. Prior to this change many fish script
strings were ignored due to how they were written (e.g., single versus
double quotes).

Fixes #4073
