$ emacs -q Makefile
M-x compile
Compile command: make -k sstt < [TAB]

at this point *Completions* just still shows targets from the Makefile
(like "sstt")

It should notice the "<" (like bash-completion correctly does), and start
instead expanding filenames.

OK, we now help it by entering the first letter of a file there, and hit
TAB. And indeed it does expand the filename correctly.

emacs-version "26.3".

I can confirm that this bug is still present in Emacs 28.

I tried looking at what's causing it to switch from Makefile target
completion to filename completion when you enter a character first, but
was unable to -- the completion code here is kinda convoluted.

Anybody got any idea what's going on here?
