- SORT_NUMERIC: new "numeric" sort specifier
pathexp.c
- globsort_numericcmp: new sort function for the "numeric" sort
specifier: all-digit names are sorted as numbers; names containing
any non-digits sort after all-digit names and are sorted
lexicographically.

The _n_u_m_e_r_i_c specifier treats names consisting solely of digits
as numbers and sorts them using the numeric value (so "2" will
sort before "10", for example). When using _n_u_m_e_r_i_c, names con-

sorted by name using the traditional behavior.

behavior of sorting by name. If set, a valid value begins with an
optional ‘+’, which is ignored, or ‘-’, which reverses the sort
order from ascending to descending, followed by a sort specifier.
The valid sort specifiers are ‘name’, ‘size’, ‘mtime’, ‘atime’,
‘ctime’, and ‘blocks’, which sort the files on name, file size,
modification time, access time, inode change time, and number of
blocks, respectively.
The valid sort specifiers are ‘name’, ‘numeric’, ‘size’, ‘mtime’,
‘atime’, ‘ctime’, and ‘blocks’, which sort the files on name, names
in numeric rather than lexicographic order, file size, modification
time, access time, inode change time, and number of blocks,
respectively. If any of the non-name keys compare as equal (e.g.,
if two files are the same size), sorting uses the name as a
secondary sort key.
For example, a value of ‘-mtime’ sorts the results in descending
order by modification time (newest first).
The ‘numeric’ specifier treats names consisting solely of digits as
numbers and sorts them using the numeric value (so "2" will sort
before "10", for example). When using ‘numeric’, names containing
non-digits sort after all the all-digit names and are sorted by
name using the traditional behavior.
A sort specifier of ‘nosort’ disables sorting completely; the
results are returned in the order they are read from the file
system, and any leading ‘-’ is ignored.

followed by a sort specifier.
The valid sort specifiers are
@samp{name},
@samp{numeric},
@samp{size},
@samp{mtime},
@samp{atime},
@samp{ctime},
and
@samp{blocks},
which sort the files on name, file size, modification time, access time,
which sort the files on name, names in numeric rather than lexicographic order,
file size, modification time, access time,
inode change time, and number of blocks, respectively.
If any of the non-name keys compare as equal (e.g., if two files are
the same size), sorting uses the name as a secondary sort key.
For example, a value of @code{-mtime} sorts the results in descending
order by modification time (newest first).
The @samp{numeric} specifier treats names consisting solely of digits as
numbers and sorts them using the numeric value (so "2" will sort before
"10", for example).
When using @samp{numeric}, names containing non-digits sort after all
the all-digit names and are sorted by name using the traditional behavior.
A sort specifier of @samp{nosort} disables sorting completely; the results
are returned in the order they are read from the file system,
and any leading @samp{-} is ignored.
