Here's a patch that cleans up the "make help" output a bit for the
documentation targets.
Currently the documentation targets are listed completely different than
all the other targets :
Documentation targets:
Linux kernel internal documentation in different formats:
xmldocs (XML DocBook), psdocs (Postscript), pdfdocs (PDF)
htmldocs (HTML), mandocs (man pages, use installmandocs to install)
with this patch they are more in line with the rest of the output :
Documentation targets:
Linux kernel internal documentation in different formats:
htmldocs - HTML
installmandocs - install man pages generated by mandocs
mandocs - man pages
pdfdocs - PDF
psdocs - Postscript
xmldocs - XML DocBook
