* mh-index.el (mh-index-search): Checking mh-find-path-run is
unnecessary. * mh-init.el (mh-sys-path): Co-locate with mh-variants, which uses it. (mh-variants): Note variable isn't meant to be accessed directly; use function mh-variants instead. (mh-variant-info, mh-variant-mh-info, mh-variant-mu-mh-info) (mh-variant-nmh-info): Co-locate next to mh-variants, which uses them. Updated to use mh-file-command-p which is more accurrate than file-executable-p which returns t for directories. (mh-file-command-p): Move here from mh-utils, since mh-variant-*-info are the only functions to use it. (mh-variant-set, mh-variant-set-variant, mh-variant-p): Use function mh-variants instead of variable. More robust. (mh-find-path-run): Move here from mh-utils.el. Mention that checking this variable is unnecessary. (mh-find-path): Move here from mh-utils.el. With the advent of MH variants and an mhparam command that doesn't work if there isn't an MH profile, we can't get libdir for running install-mh. So don't bother. If there's an issue with the environment, direct the user to install MH and run install-mh (closes SF #835192). Don't read ~/.mh_profile directly. Use mh-profile-component which uses mhparam (closes SF #1016027). * mh-utils.el (mh-get-profile-field): Rename to mh-profile-component-value. Add colon to search removing unnecessary addition of colon to field in mh-profile-component. (mh-profile-component): Modify call to mh-profile-component-value accordingly. Move next to mh-profile-component-value. (mh-find-path-run, mh-find-path, mh-file-command-p): Move to mh-init.el. It makes sense that code that is only run once per session (more or less) is in mh-init.el rather than cluttering mh-utils.el. (mh-no-install, mh-install): Delete.
