[PATCH] emacs: sanitize subject in replies

[Jani Nikula]

Commit a7964c86d125 ("emacs: Sanitize authors and subjects in search
and show") added sanitization of header information for display. Do
the same for reply subjects.

This fixes the long-standing annoying artefact of certain versions of
mailman using tab as folding whitespace, leading to tabs in reply
subjects.
