[PATCH 0/5] Fixes for %empty insertion

[Akim Demaille]

Running --update on more grammars revealed a case when some bits of
the grammar were removed while inserting missing '%empty's.  While
addressing this, a few clean up opportunities came up.

Akim Demaille (5):
  maint: update gnulib-po/.gitignore
  style: clarify the use of symbol_lists' locations
  style: use consistently *_loc for locations
  tests: don't duplicate the portability prologue
  fixits: be sure to preserve the action when adding %empty
