Hello,
It seems that using a non-absolute MH variable doesn't work when an MH
program chdir's and exec's a child that needs to read the
profile. (Example below involving show and mhshow.)
By inspection, setting MH to the resolved, absolute pathname inside
context_read suffices to solve the problem I've encountered, but I don't
know the overall codebase well enough to understand if it goofs up
something elsewhere.
Thank you,
Richard
