Bug#181585: wc.1: name synopsis should include "count" keyword

[Alfie Costa]

A .diff for '/usr/share/man/man1/wc.1.gz' is attached.
Before:
        wc \- print the number of newlines, words, and bytes in files
After:
        wc \- for text files, count newlines, words and bytes
Notes:  when seaching with 'apropos', "print" and "number" are vague to 
the point of being useless.  On my system:

        apropos number | wc -l
        160     
        apropos print | wc -l
        221
        apropos count | wc -l   # fewer
        22
An unqualified 'files' is worse:
        apropos files | wc -l
        379
        apropos file | wc -l
        1147
        apropos "text files" | wc -l  # fewer
        9
        apropos "text file" | wc -l   # ""
        12
Trivia:  a Bell Labs Unix manual says "wc - word count".
HTH...
