-sed -n -e 's@^//usage:\([ \t].*\)$@\1 \\@p' -e 's@^//usage:\([^
\t].*\)$@\n\1 \\@p' \
+TAB="$(printf '\tX')" ; TAB="${TAB%X}"

Why   .*   turned into    ..*    ?

Figuring out that second sed -e CMD has an embedded newline
took some time.

I'm going with this:

TAB="$(printf '\tX')"
TAB="${TAB%X}"
LF="$(printf '\nX')"
LF="${LF%X}"
sed -n -e 's@^//usage:\([ '"$TAB"'].*\)$@\1 \\@p' \
       -e 's@^//usage:\([^ '"$TAB"'].*\)$@\'"$LF"'\1 \\@p' \
        "$srctree"/*/*.c "$srctree"/*/*/*.c \
