https://posix.rhansen.org/p/gettext_draft Lines 1202..1211
In line 1164, the argument to the -K option is called 'pattern'. Issue: In lines 1202..1211 it is called 'keyword'. Suggestion: Use the same term 'pattern' here as well, instead of 'keyword'. Rationale: In the 1st, 3rd, and 4th case, it is a misnomer to call the argument a "keyword".
