Subject: Documentation/Makefile: break up texi pipeline
X-Git-Tag: v1.6.3-rc0~51^2~1^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c6a5ad21e57ce38a0add04a2708ccf02ed17af39;p=git.git

Documentation/Makefile: break up texi pipeline

Most shells define the exit value of a pipeline as the exit value
of the last process. For each texi rule, run the DOCBOOK2X_TEXI
tool and the "fixup" script in their own non-pipeline commands so
that make will notice an error exit code.
