3# The parser used to break dependency lines at ';' without regard for
4# substitution patterns.  Back then, the first ';' was interpreted as the
5# separator between the dependency and its commands.  This (perhaps coupled
6# with the new handling of .for variables in ${:U<value>...) caused
7# interesting results for lines like:
8#
9# .for file in ${LIST}
10#   for-subst:       ${file:S;^;${here}/;g}
11# .endfor
12#
13# See the commit to unit-tests/forsubst (without the .mk) from 2009-10-07.
