Speaking of which, for some time now, I have wished that AT_DATA and
AT_CHECK could handle files that don't end in newline.  I ended up doing
this in the M4 autotest sources:

| AT_SETUP([__@&address@hidden)
| dnl Unfortunately, AT_DATA does not make it easy to create files without
| dnl a trailing newline.
| [echo $ECHO_N "__line"__:__"file__$ECHO_C"] > nested
...

Perhaps I should look at using ECHO_C/ECHO_N technology to make it
possible to support AT_DATA([no newline]).
