test/inc/test-eom-align: Fix tests; they've never worked.
Instead of cycling through lots of mbox sizes, $STDIO_BUFSZ was always
used as the desired size resulting in tests A and B being duplicated 221
times each. Slowly, if using valgrind. The tests fail now they're
fixed.
`$Test' was being interpolated into the output, but has never existed.

Remove support for aliases based on Unix groups.
Remove support for expanding aliases based on group membership (=) and

of a discussion on nmh-workers; these features were of dubious value, likely

After further reflection, I decided I didn't like that previous
implementation. Instead, allocate two ptys and connect one to standard
input and the other to standard output and standard error of the child
process. After the first data is received from the slave, close the
master connected to standard input; that will generate an EOF on input
to the child process. This ends up being much cleaner than looping and
waiting to send the EOF character to the child process.

Apparently on Linux if a slave pty is closed, instead of the master
getting an EOF they get an EIO, which strikes me as unfriendly. So
make sure we exit the main read loop without complaint on an EOF or
error.

It's been decades since a lex(1) didn't follow POSIX and treat `{foo}'

If the profile component nmh-storage was a single character, e.g. the
relative directory `d', then it would be dropped from the output path so
instead of `d/foo' being written, `/foo' would probably fail. I think
this was due to a faulty check for nmh-storage being `/'. Add a test
