[bug #57638] Regression: -me's .nm macro broken as of commit 2cc968c7

[Bjarni Ingi Gislason]

Follow-up Comment #3, bug #57638 (project groff):


[comment #2 comment #2:]
> G Helffrich posted a patch:

  The provided patch uses 'd' instead of 'r' in the test.

    Add a test for the numeric registers "_#p" and "_#f"
in the macro ".nm",
before they are used.

  Changed lines:

-.      ps \\n[_#p]
-.      ft \\n[_#f]
+.      if r _#p .ps \\n[_#p]
+.      if r _#f .ft \\n[_#f]
