How did 'xrm' become a file name? 

It happened after I added the "-exclude-from=EX -P -r"
to an alias... but it happens when I use
the binary directly (i.e. no alias).

I was expecting 'xrm' to be a pattern that was searched
for in the files starting at the current directory.

"New" to me -- use of the -exclude-from option.
Of note: EX contains:
*.orig
*.1
*.1.in


Ideas?  Doesn't seem like correct action...

Because you omitted a "-" before "-exclude", and that caused your pattern to be 
'xclude-from=EX'.
