Simplify journal_entry_pr(), rename to journal_entry_write()

journal_entry_pr(S, N) writes up to N characters from zero-terminated
string S.  journal_input() passes -1 for N to write all characters.
Unclean.  SIZE_MAX would do, but it's C99, and MSC doesn't provide it.

Simplify journal_entry_pr() to write exactly N characters.  This makes
it more similar to write() than to pr(), therefore rename.
