Subject: [PATCH] cut: -w: avoid per character function calls

Adding a couple of inlining hints to the compiler
gives a 30% boost in raw character processing performance
in cut_fields_mb_any().

  $ yes $(yes eeeaae | head -n10K | paste -s -d,) | head -n10K > ll.in

  $ time LC_ALL=C.UTF-8 src/cut-before -f1 -w ll.in >/dev/null
  real	0m2.279s

  $ time LC_ALL=C.UTF-8 src/cut-after -f1 -w ll.in >/dev/null
  real	0m1.619s

* src/cut.c (scan_mb_blank_field): Tag as inline.
(scan_mb_delim_field): Likewise.
