ce10d5ca08 fix(emacs/lean-flycheck.el): use flycheck-increment-error-columns instead of advice 
Comment from @lunaryorn (flycheck author):

"Please don't use an advice to increment error columns. Flycheck has
:error-filters and there is even a built-in one exactly for your use
case: :error-filter flycheck-increment-error-columsn. Generally never
use advises at all in libraries or modes. They are for user
configuration, or as a very last resort only."

11fbee269b fix(frontends/lean/parser): must save state of name_generator in parser snapshot 
To provide typing and auto-completion information, we create a
background process by starting lean with the option --server.
In "server" mode, we create snapshots of the parser state.
The idea is to be able to quickly reprocess a file when the user makes a
modification. This commit fixes a bug in the snapshot operation.
It was not saving in the snapshots the unique name generator used by the parser.
By creating a fresh name generator, we may accidentally
assign the same internal name to two different constants.
This bug triggered the crash described in issue #593.

This commit fixes the test in the comment
https://github.com/leanprover/lean/issues/593#issuecomment-101768484

This commit also adds a smaller version of the problem to the test suite

0b57f7d00a refactor(library/tactic): refine interface between tactic and proof-term modes 
Some constraints were being lost with the previous interface.
This is why we had a workaround in fintype.lean.

We can also remove some hacks we have used in the past.

a_i is definitionally equal to b_i for each i in [1, n]

~~~
if(<constant>)

True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number. False
if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, the empty
string, or ends in the suffix -NOTFOUND. Named boolean constants are
case-insensitive. If the argument is not one of these constants, it is
treated as a variable.

3d79f89f5e fix(emacs/lean-mode): lean-execute 
shell-quote-argument also escapes '~' into '\~' which causes a problem.
This fix first calls 'f-full' to get a absolute path, then call
shell-quote-argument.

enforce the goal type.
