[GNC-dev] Small changes to comment text, mostly in gnucash/import-export/import-main-matcher.h

[Kevin Buckley]

For reasons I'll not go into (?!) I happened to notice that  there
are a few  places in the source where the text reads, eg,

* @param info. A pointer to a the  <struct_name> structure

Not clear if the "a the" was meant, but, as there are a shedload of
"A pointer to the <something>" strings, but no "A pointer to a <something>"
strings that I could grep, in case it helps tidy up the codebase, a recent grep
on the maint branch returned:

./gnucash/import-export/import-main-matcher.h: * @param info. A
pointer to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./gnucash/import-export/import-main-matcher.h: * @param info A pointer
to a the GNCImportMainMatcher structure.
./libgnucash/engine/gnc-numeric.h: *  @param a the ::gnc_numeric value
to convert
./libgnucash/app-utils/calculation/expression_parser.c: *         The
first parameter is a pointer to a the first element in

I also note that the first of those has a periof after the parameter name,
whilst none of the others do.

HTH, and thanks, as always, for GnuCash,
