Spelling errors in pcb

[أحمد المحمودي (Ahmed El-Mahmoudy)]

The attached patch fixes some spelling errors in pcb.

There is also an error that I didn't fix in the patch, because it exists a lot in the code & documentation: "wether" should be corrected to "whether"

New patch includes fixes for [wW]ether spelling errors.

Hi Ahmed,

Thanks for the diffs.

It would make patching a little bit easier for me if you could provide "git" generated patches, this would solve attribution in the process and would list you as the author of the patch (and ever lasting fame as a side effect).

Please note that "options.texi" and "pcb.html" are generated files, and as such do not require patching.

Instead I applied the corrections in the sources files only.

The same goes for the ".po" files, although patching these is not a lost effort (these are not generated during a build, unless "make update-po" is manually invoked).

I updated the commit in the topic branch.

Will be merged after review.

Kind regards,

Bert Timmerman.
