Yes, this is supposed to be a tab size. Unfortunately, it currently
isn't working (thanks for noticing and reporting). I have just posted a
patch to fix this, though (see
http://code.google.com/p/texworks/issues/detail?id=89) which Jonathan
hopefully commits to svn soon.
BTW: It's supposed to read "px" instead of "pt" (this is also fixed by
my patch). And it's not generally 6 characters, as you can also work
with proportional fonts in the editor. It is indeed the amount it says
it is, e.g. 32 px.

This depends on the content of your
configuration/auto-indent-patterns.txt. The default options are:
"Whitespace only"
Whenever you hit the [Return] key to start a new line from a line that
started with whitespace chars (space, tab), those whitespace chars will
be copied to the beginning of the new line.

"TeX comments"
Same as "Whitespace only", but if you have one or more "%" (LaTeX
comment chars) at the beginning of the old line they (and successive
whitespaces) will be copied to the new line, too.

"dtx prefixes"
Same as "TeX comments" except that the comment char "%" is only copied
if the line has certain formats. Most notably, if the comment starts
with "\begin{macrocode}", no comment character will be added. This is
intended primarily for LaTeX package & documentation writers, AFAIK.
