Package: mutt
Version: 1.4i
Severity: normal
-- Please type your report below this line
I have found a weirdness in quote_regexp.
In order to see it, first set the style for quotedN to something
different from quoted, say:
color quoted green black
color quoted1 cyan black
color quoted2 cyan black
color quoted3 cyan black
color quoted4 cyan black
color quoted5 cyan black
color quoted6 cyan black
color quoted7 cyan black
color quoted8 cyan black
color quoted9 cyan black
Then, let's take an example:
>foo
> foo
> foo
>>bar
> >bar
> > bar
> > bar
> > bar
I would like the first free line to be in quoted style, and the rest
in quoted1.
I set my quote_regexp to a sensible value which would work for most
people:
set quote_regexp="^(>[ \t]*)+"
but it doesn't have the expected effect.
I experimented a little with this, and found the following:
1. quote_regexp="^(>[ \t]*)+" does not work as I expected.
2. quote_regexp="^(> *)+" works, although it doesn't detect tabs.
3. quote_regexp="^(>[ ]*)+" works too.
4. quote_regexp="^(> *\t* *)+" works as I expected.
5. quote_regexp="^([ \t]*>)+" works, but is slightly different.
My guess is that "[ \t]" is internally interpreted the same way my
(...)+ is interpreted and makes it fail. I had expected that the
outermost repeated pattern (if that makes any sense) would be the one
used for quotedN.
Is this a bug? If not, what is the rule for computing N for quotedN,
and could you please add it into the documentation (unless I
overlooked, there are just 3 lines under 6.3.176. quote_regexp talking
about it)?
Thank you.

Hugo

On the following configuration
------------------------(snipp)---------------------
color quoted red default
color quoted1 magenta default
color quoted2 green default
color quoted3 yellow default
------------------------(snipp)---------------------
the different quoting levels are colorized randomly in varying the color
when scrolling through the mail in the pager, and finally the color is
not always the one which is specified in the muttrc.

>How-To-Repeat:
>Fix:
Mutt uses "quote_regexp" to identify which lines are quotes.
It keeps track of the exact(!) matching string to compare
different quote levels for the "quotedN" coloring items,
it does not(!) ignore white space when comparing:
' > >' is the _not_ the same as '>>'.
Even though both have the same numerical quote level (2),
different quote strings are typically produced by different
authors, therefore should be treated as separate quote level.
