[Jim Meyering]

I looked into this bug:

    http://bugzilla.redhat.com/463556

and wrote the patch below.
I'll push it soon, probably tomorrow, after a test case.

Subject: [PATCH] seq -0.1 0.1 2: print 2.0 also when locale's decimal point is 
","

* src/seq.c (print_numbers): Use strtold, not c_strtold to convert
from just-formatted-using-asprintf string back to double, since
asprintf may have used something other than "." as the decimal point.
Reported by address@hidden as <http://bugzilla.redhat.com/463556>.

    $ LC_ALL=cs_CZ.UTF-8 seq -0.1 0.1 2|grep 2.0
    [Exit 1]
    $ seq -0.1 0.1 2|grep 2.0
    2.0
