Log message:
net/unison-snapshot: Update to 2.51.91

Upstream changes are one bug fix primarily affecting Windows and
non-relevant changes in opam packaging.

Log message:
net/unison-snapshot: Update to 2.51.90

This is an rc for 2.52.0 and has no significant changes from the
previous snaphot.

upstream changes: minor/bugfixes

Log message:
net/unison-snapshot: Fix MKPIE logic

ocaml.mk defines MKPIE_SUPPORTED=no, but this was after bsd.prefs.mk
so _PKGSRC_MKPIE was already set to yes.  This was made harder to
debug by options.mk including bsd.prefs.mk.   Reorder to load ocaml.mk
earlier.

Log message:
unison-snapshot: Update to 2.51.70

This is an alpha for 2.52.0 and contains significant changes.

While just upgrading and using it should work, it has not received
enough testing to be called beta.  In particular the new formats have
not been tested with big endian processors.

## Changes in 2.52.0

   * Feature negotiation, compatible with 2.51.
   * New archive format (independent of ocaml version, based on umarshal)
     Upgrade is automatic.
   * New wire protocol (independent of ocaml version, based on umarshal)
     New protocol is used if both sides are >= 2.52.0.
   * Support for unix-domain sockets
   * Many bugfixes and minor improvements
   * ocaml compatibility is now >= 4.01
   * NEWS is now in NEWS.md and not in the manual

Log message:
net/unison-snapshot: Update to 2.51.5.70.1

upstream changes are the rpc version negotiation incorrectly listed
before, which actually had some features that could be negotiated.

Log message:
net/unison-snapshot: Update to 2.51.5.70.0

upstream changes: Add RPC protocol negotiation (but there is not yet a
new protocol).  Should interop with all 2.51.x.

Log message:
net/unison-snapshot: Update to 2.51.4.70.4

Upstream changes are very minor.  (This is a 2.51.5 release
candidate.)
