BurnZeZ reported this the other day. It seems like if we have
a pipeline that looks like:

	fn foo{cat < <{echo hi}}

then the '<' will get merged in /env/'fn#foo'. This change
fixes pcmd to add a space. It looks to me like this is the
only token that can get merged this way by pcmd, but I'd
appreciate someone else taking a look for missed cases:
