comparison toys/other/pmap.c @ 1043:acf7bb2b99e2 draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Introduce libbuf analogous to toybuf but for use by lib/*.c. Change readfile() semantics to be able to read into an existing buffer, or malloc its own if that's NULL.
