Using find2perl(1) tool to translate file name glob `a?b'
to a Perl code.
The `?' glob is translated erroneously and resulting Perl
code matches different names than the find(1) tool.
Glob expression translator has been corrected not to
copy the question mark to resulting regular expression.
find2perl(1) matches the same files as the find(1)
tool when using globs with a question mark.
