(general_numcompare): Use strtod, not xstrtod.
Do not consider partial conversions to be errors.
Put -infinity at the start, and +infinity at the end;
follow +infinity with NaNs (sorted by bit pattern),
and finally by conversion errors.
(struct line, findlines, compare, checkfp, mergefps, sort):
A line now includes its trailing newline.
(findlines): Do not replace newline with NUL.
(memcoll, keycompare): Work even if the data to be compared are
adjacent strings; this is possible now that lines contain the
trailing newline.
(fillbuf): Always have an unused byte at the end of the buffer,
since memcoll and keycompare want to modify a byte after the last line.
(sortalloc, mergealloc): Increase by 1, for trailing byte.
characters properly when comparing with LC_COLLATE semantics.
(NLS_MEMCMP): Remove.
(memcoll): Renamed from strncoll.
Take separate lengths for each string.
This function is now invoked only when need_locale.
(keycompare): Don't copy strings when ignore and translate
are both NULL.
months, as this conflicts with POSIX.2 and is tricky to boot.
(FLOATING_COMMA, NLS_STRNCMP, NLS_MAX_GROUPS,
NLS_ONE_CHARACTER_STRING): Remove macros no longer used.
(nls_grouping, nls_fraction_found, nls_month_found, nos_monthtab,
nls_months_collide, nls_keyhead, us_monthtab): Remove variables no
longer used.
(struct nls_keyfield): Remove types no longer used.
(strncoll_s2_readonly, nls_set_fraction, look_for_fraction,
nls_month_is_either_locale, nls_numeric_format): Remove functions no
longer used.
(monthtab): Now has the role that us_monthtab had, but it's const only
if ENABLE_NLS is not defined.
(C_DECIMAL_POINT): Renamed from FLOATING_POINT. All uses changed.
(MONTHS_PER_YEAR): Renamed from NLS_NUM_MONTHS. All uses changed.
(struct_month_cmp): Renamed from nls_sort_month_comp. All uses changed.
Use strcmp, not strcoll, since the user doesn't care about collating
here.
(inittables): Read locale data into monthtab, rather than modifying a
separate month table and futzing with indirection. Do not worry about
colliding months, since we no longer autodetect month locale.
(fraccompare): Don't set no-longer-used variable nls_fraction_found.
(getmonth): Use strncmp to compare months, since user doesn't care
about collating here. Fix bug where code incorrectly assumed that
strlen (monthtab[lo].name) == strlen (monthtab[ix].name).
(keycompare, main): Don't autodetect month locale.
(compare): Don't use NLS_MEMCP in code that can't be executed if
need_locale is false, as NLS_MEMCP is equivalent to memcmp in that
case.
(sort, insertkey, main): Don't autodetect numeric locale.
running `id USER' for some USER that is listed on the RHS in /etc/group.
From Sander van Malssen.
Add some curly braces, use STREQ, reverse the sense of a test
and use `continue' to save a level of nesting.
