Subject: When determining the path of the script inside mhmail, handle case
X-Git-Url: http://git.marmaro.de/?a=commitdiff_plain;h=61cf1467a9efaf4869f22eca6aa3ece2a74f10f6;hp=61cf1467a9efaf4869f22eca6aa3ece2a74f10f6;p=mmh

When determining the path of the script inside mhmail, handle case
where $0 is just the script name, without any directory.  Bourne
shell does that if the script is found using PATH.
