Subject: [PATCH] tmac/strip.sed: Keep the protection (and visibility) of
 spaces

  Do not remove the protection (\") of spaces at the end of a
definition of strings (line '/.[ad]s/s/\([^         ]*\)\\"/\1/'
removed)

  Make the change only apply to definitions of strings
(change '.' to '\.[     ]*'

  The comment escape (\") after a space in the definition of strings is
used to protect spaces, make them visible and significant.

  Commit ae59ee569eb5cddab8bdf12a8009bd1b907a8205 is thus partially
reversed.
