Sure. But I am still curious as to the purpose intended by @ in the
first place if anybody knows.
From dist(1):
See comp(1) for a description of the -editor and -noedit switches. Note
that while in
the editor, the message being resent is available through a link named
"@" (assuming
the default whatnowproc). In addition, the actual pathname of the
message is stored
in the environment variable $editalt, and the pathname of the folder
containing the
message is stored in the environment variable $mhfolder.
It is provided as a fixed-name alias for the file being edited should you want
to
run an external command on the composition file. (E.g. '!spell @'.) Remember
that this functionality pre-dates widespread availability of job control, or
even cursor-addressable terminals (think DecWriter attached to the VAX).
The idea is that ./@ will always provide an invariant and memorable name for
the composition file. Moving it to `mh-path`/@ defeats that goal.
I like Ken's idea about having a switch to turn this on and off. People who
don't want/need the link could disable it in .mh_profile.
