Closes #53
Further refine parseExprList indentation heuristic

Closes marijnh/tern#221
Fix special case to handle regexps that start with =

Closes #55
Improve error message for ++/re/

Closes #54
Fixed: replace absolute with relative require, remove unsupported --trackComments from usage.

Unless I'm missing something, the simple relative path "../acorn.js" is exactly equivalent to the absolute path being constructed in the old code.
Formatting

Just being consistent.

In every other place where a between comparison is done, the lower limit is on the left. It's a whole lot easier to see it's a between comparison when the limits are in order.
Add support for bizarro <!-- and --> behavior

Issue #62
Use correct paragraph separator for newline

0x2089(8329) is Subscript nine
0x2028(8232) is Line separator
0x2029(8233) is Paragraph separator
Work around docco leaving in a <!-- comment start

Closes #66
Add .gitignore and .tern-project
Different approach to working around html comment issue
Just want to be a little clearer what is happening to the node var declared earlier.
Fix wrong end position for VariableDeclaration nodes

It should include the semicolon.

Closes #67
Fixed: skipSpace did not consider 8232 and 8233 as eol, but elsewhere it was.

Both readString and skipLineComment considered 8232/8233 as eol, but skipSpace itself would not increment the line counters if they were found.

Previously 8232/8233 were listed in nonASCIIwhitespace, but since that is only used within skipSpace and those values are checked separately, they could be removed from nonASCIIwhitespace.
Remove invalid of tokLineStart

This is only tracked when locations are on, so it can't be used
unconditionally.

Closes #71
Fixed: tokLineStart and tokCurLine have no meaning if options.locations is false.

Everywhere else (except one place which is a bug) those variables only appear within an `if (options.locations)` block.
