Maybe something like the script below to break up the MAINTAINERS file
into separate files.  It also uses underscores for spaces in the
section header -> filename translation.

This seems to work OK except for this single section which doesn't
follow the normal single line section header style.

EDAC-XGENE
APPLIED MICRO (APM) X-GENE SOC EDAC
M:     Loc Ho <lho@apm.com>
S:     Supported
F:     drivers/edac/xgene_edac.c
F:     Documentation/devicetree/bindings/edac/apm-xgene-edac.txt

That one would need manual fixup.
