Thanks. It works great. GIT_PARSE_WITH is now:

AC_DEFUN([GIT_PARSE_WITH],
[[PACKAGE=m4_toupper($1); \
if test "$withval" = "no"; then \
    GIT_APPEND_LINE(NO_${PACKAGE}=YesPlease); \
  elif test "$withval" != "yes"; then \
    GIT_APPEND_LINE(${PACKAGE}DIR=$withval); \
  fi; \
]])# GIT_PARSE_WITH

I suspect that AS_HELP_WITH does some strange quoting, or stripping. Both
[=PATH] and [[=PATH]] produces =PATH in ./configure --help output.
When using @<:@=PATH@:>@ I get [=PATH], but the description of option begins
line below.

Any ideas for name of MY_APPEND_LINE(LINE)/GIT_APPEND_LINE(LINE) macro,
which as a result adds line to output (e.g. LINE = "NO_CURL=YesPlease")?

Thanks for all suggestions
