.jvmopts memory options ignored unless they are first in the file

[NirvanaNrv]

steps

With sbt 1.3.8 Windows setup, use a local .jvmopts such as
-XX:ReservedCodeCacheSize=128m
-Xss2m
-Xmx1536m
-Xms1512m

problem

The jvm launches with the default memory settings instead of those from the file.

expectation

Uses them.

notes

In the :addDefaultMemory section, there is a for /F %%g in ("!_JAVA_OPTS!"), which would work only for the first argument of this space separated string. I had success replacing it with just for %%g in (!_JAVA_OPTS!), but I did not push through the thought about possible spaces or quotes within jvm options. The workaround of putting -Xmx or -Xms first is fine, once you know it.

@NirvanaNrv Thanks for the report!

This is related to the "=" bug in our windows bat argument parsing. If you use another argument other than -XX:ReservedCodeCacheSize=128m (which has the =) in it, it would work.
