Following patch fixes inline images with content dispositions sent

Content-Type: image/gif;

Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename="foo.gif"
The ";" was deleted in the original code. I changed it to replace
it with a space.
This is not the proper fix since the return value of the function does
not contain the proper value for the first list item. Ie. $disp does
not contain just "inline" but "inline filename="foo.gif"" (or
inlinefilename="foo.gif" w/o the patch). Your quick fix works because
the mhexternal.pl filter uses a regex to check the value instead of
using the eq operator.
The proper fix is to deal with the case when the following can
occur:
Content-Disposition: inline;filename="foo.gif"
BTW, this is how the field will look when unfolded. readmail.pl
made the assumption that there would always be a space after the
semi-colon if a semi-colon is present.
In sum, first try extraction assuming there is a semi-colon. If it
fails, then there is a disposition value w/o a filename parameter, or
any other parameters.
