.gitignore files on windows produce invalid regular expressions

[bbsdddougla]

When using build-if-changed on windows, the glob patterns generated for ignores are invalid. For example, this .gitignore file produces the following error:

// .gitignore
obj/

>SyntaxError: Invalid regular expression: /^(?:C:\myproj\bcat\obj\)$/: Unterminated group 0> at new RegExp (<anonymous>) 0> at matchAny (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\node_modules\recrawl\lib\recrawl.js:87:32) 0> at Object.createMatcher (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\node_modules\recrawl\lib\recrawl.js:129:39) 0> at GitIgnore.test (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\lib\gitignore.js:46:39) 0> at Object.opts.filter (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\lib\cli.js:19:46) 0> at opts.filter (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\lib\index.js:15:25) 0> at recrawl_1.crawl.enter.dir (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\lib\index.js:20:34) 0> at crawl (C:\Users\adude\AppData\Roaming\nvm\v10.18.1\node_modules\build-if-changed\node_modules\recrawl\lib\recrawl.js:62:25) 0> at process._tickCallback (internal/process/next_tick.js:68:7) 0> at Function.Module.runMain (internal/modules/cjs/loader.js:834:11)
