[Nano-devel] treating underscore as alphanumeric

[Benno Schulenberg]

Hi all,

Having bound the functions prevword and nextword to other keys
so they are now accessible to me, I find they don't quite behave
as I would wish, both with wordbounds set and unset.

With wordbounds set, it will treat all punctuation characters as
alphanumeric, so when encountering "function(variable, other)"
it will jump from function to other, but I want it to jump from
function to variable.  It does that when wordbounds is unset,
but then it will treat for example "MB_CUR_MAX" as three words --
not what I want either.

So I would like to propose to add in src/chars.c, to the function
is_alnum_mbchar(), this:

    if (strncmp((const char*)c, "_", 1) == 0)
        return TRUE;

Maybe this should be made dependent upon a settable option, say
"underscores", but I think underscore is so much considered a
substitute alphanumeric, that this won't be necessary.

What do you say?

Benno
