Guideline:
- do NOT translate strings in error() messages, or in dprint()!
- delete obviously useless developer prints while at it
- change obvious developer prints from print to dprint (even in comments),
  unless in developer-only functions (e.g. *dumptree*)
- mark translatable strings with _()
- if a translatable string is a strcat monster, change it to sprintf
- if code loads files with text, allow loading
  <filename>.cvar_string("prvm_language") in preference
- test by:
  find . -type f -not -name \*.po | xgettext -LC -k_ -f- gamecommand.qc
- interesting vi macros:
  :map # /"<return>
  :map ' i_(<esc>2f"a)<esc>/"<return>
