LU-9679 general: add missing spaces near punctuation

LU-9679 general: add missing spaces near punctuation

Many places in lustre fold a long string onto multiple lines, usually
at word breaks.  Sometimes the word-break has punctuation, such as
comma, colon, or period, but needs a space as well to be properly
readable.  Because the string is folded, the missing space isn't
immediately obvious in the code.

This patch adds those spaces after punctuation where is seems to be
needed, and joins the affected strings onto a single line, in accord
with current policy.
