comments in .mailrc treated inconsistently

[Roland Winkler]

Symptoms:

The functions build-mail-abbrevs and build-mail-aliases are very
similar. However, build-mail-abbrevs ignores comments (anything in a
line that follows `# ') while build-mail-aliases doesn't do that.
I do not know whether other programs like /bin/mail which use the
.mailrc file, too, understand such comments. However, I find these
comments very convenient and I suggest that the following lines from
build-mail-abbrevs should be included in build-mail-aliases, too.

          ;; Delete comments from the file
          (while (search-forward "# " nil t)
            (let ((p (- (point) 2)))
              (end-of-line)
              (delete-region p (point))))
          (goto-char (point-min))

In this way, the functions build-mail-abbrevs and build-mail-aliases
would treat comments consistently.
