[PATCH 0/6] fix a missing context indent, and scan-skel rework

[Theophile Ranquet]

The previous patches left a case where the context of an error message
was still unindented, and prefixed. This was because it came from an
m4 @complain, and required a bit of a rework of scan-skel.

This patch does the said rework, and addresses the issue. The code from
scan-skel has imho been made simpler, and more obvious, though, much
to my regret, not any shorter.

Theophile Ranquet (6):
  errors: pointerize complain_at_indent
  errors: factor b4_error @directives
  errors: support indented context info in m4 macros
  scan-skel.l: split @directive functions
  scan-skel.l: recognize the @directives directly in scanner
  scan-skel.l: change fail_for_invalid_at prototype
