Subject: gen-strtab.awk: Allow repeated whitespace in one-line strings.
X-Git-Url: https://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/c3f53b697f5dd5ecd5a5f74e94ec0fd55b0f2764

gen-strtab.awk: Allow repeated whitespace in one-line strings.

The documentation says that, for a one-line string, all whitespace
immediately following the identifier is deleted.

It does not say that anything happens to other withespace on the line,
but it turns out that consecutive sequences of whitespace are replaced
by a single space.  This is unexpected.

Fix up the script so that doesn't happen, and add a test for this.
