t4034/cpp: actually test that operator tokens are not split
8d96e7288f2b (t4034: bulk verify builtin word regex sanity, 2010-12-18)
added many tests with the intent to verify that operators consisting of
more than one symbol are kept together. These are tested by probing a
transition from, e.g., a!=b to x!=y, which results in the word-diff
[-a-]{+x+}!=[-b-]{+y+}
But that proves only that the letters and operators are separate tokens.
To prove that != is an unseparable token, we have to probe a transition
from, e.g., a=b to a!=b having a word-diff
a[-=-]{+!=+}b
that proves that the ! is not separate from the =.
In the post-image, add to or remove from operators a character that
turns it into another valid operator.
Change the identifiers used around operators such that the diff
algorithm does not have an incentive to match, e.g., a<b in one spot
in the pre-image with a<b elsewhere in the post-image.
Adjust the expected output to match the new differences. Notice that
there are some undesirable tokenizations around e, ., and -. This will
be addressed in a later change.
