* build-aux/bootstrap (found_aux_dir): Also transliterate - in
prerequisite name.
(print_versions): Be robust to any \ in $buildreq.

Sorry for Thunderbird's bug corrupting the formatting of Justin's mail.

Hmm, looking at this further, I note that bootstrap is already doing
a loop over all of $buildreq, reporting each failure as it goes,
and then, after reporting all failures, merely reprinting the entire
list of requirements.  Maybe the thing do is just leave the error
messages, and skip reprinting $buildreq; at any rate, that's simpler
than munging $buildreq to include details about the successful
version checks.  So I didn't do anything about this second suggestion
on the missing pre-req output.
