Option to keep spaces before inline comments

Add a keepSpaces or keepSpacesBeforeLineComments similar too keepLines that preserves the spaces between values and inline comments at the end of the line.

This will help to avoid unnecessary changes when formatting tsconfig.json files:

Original:

    /* Language and Environment */
    "target": "es2016",                                  /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
    // "lib": [],                                        /* Specify a set of bundled library declaration files that describe the target runtime environment. */

Formatted:

    /* Language and Environment */
    "target": "es2016", /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
    // "lib": [],                                        /* Specify a set of bundled library declaration files that describe the target runtime environment. */

Diff:

     /* Language and Environment */
-    "target": "es2016",                                  /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
+    "target": "es2016", /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
     // "lib": [],                                        /* Specify a set of bundled library declaration files that describe the target runtime environment. */

Commencez par lire l’option keepLines existante et la pull request associée, puis suivez l’API du formateur qui gère les commentaires en ligne. Utilisez les exemples de tsconfig.json comme référence du comportement : lorsque la nouvelle option est activée, les espaces avant les commentaires de fin de ligne doivent être conservés sans modifier les autres éléments du formatage.
