fixed pair! op/action bug
Files beginning with .. are skipped (http://issue.cc/r3/1899)

Only the files . and .. are special in Posix and Windows; other files
starting with . or .. are considered normal. R3 was skipping all files
starting with .. when reading a directory. This fixes that.
REQUEST-FILE/multi returning multiple files is missing the last / in the filenames

See http://issue.cc/r3/1891 for details. It looks like the path wasn't
getting a trailing / added to it when multiple files were selected, so
when the filenames were appended that / was missing.
Better comments for sys/load-header

The comments of sys/load-header were slightly outdated, and not detailed
enough for people to understand how it works. They also didn't mention
the two embedding methods, nor were they correct in asserting that
checksums didn't work for script-in-a-block.

The new comments mention a gotcha about the 'content header, the
embedded script methods, multi-script support, and the reason that the
body of a script-in-a-block is returned decoded.
Comment explaining a tricky situation in startup

There was the "Would be nice to use DO for this section." comment, but
it didn't explain why. In the past this ambiguity led to CATCH/quit
being added to this code, which caused http://issue.cc/r3/1734 - we
don't want errors like that recurring.
Prevent misunderstandings like http://issue.cc/r3/1913

By design, TRANSCODE/error inserts the error, that it would otherwise
trigger, in the place where it would insert a value if there was no
error. This provides valuable context for the error, and can be used to
help in recovery of the transcoding process if you want to. This doc
string tweak makes that more clear so there will be less confusion about
this.
Fix CC#1865: resolve/extend/only crash

For RESOLVE/extend, the source context was extended instead of the
target context. This mistake can invalidate assumptions and lead to
invalid memory accesses, and, in turn, to crashes.
