Starting error messages with a capital letter complicates things when
text can get interpolated both at the beginning and in the middle of
an error message. The next patch will do that. Switch to lower case
to keep it simpler.
For what it's worth, the GNU Coding Standards advise the message
"should not begin with a capital letter when it follows a program name
and/or file name, because that isn’t the beginning of a sentence. (The
sentence conceptually starts at the beginning of the line.)"
While there, avoid breaking lines containing multiple arguments in the
middle of an argument.

Show text up to next structural character, whitespace, or quote
character instead of just the first character.
Forgotten quotes now get reported like "Stray 'command'" instead of
"Stray 'c'".

Consistently enclose error messages in double quotes. Use single
quotes within, except for one case of "'".

The error message for forgotten quotes around a name shows just the
name's first character, which isn't as nice as it could be. Same for
attempting to use a number.
