346 | |
347 | Quotes an item to become safe against spaces |
348 | in shell interpolation. An item is enclosed |
349 | in double quotes if: |
350 | |
351 | - the item contains spaces in the middle |
352 | - the item does not start with a quote |
353 | |
354 | This happens to avoid shell interpolation |
355 | problems when whitespace is present in |
356 | directory names. |
357 | |
358 | This method uses C<commands_quote> to determine |
359 | the correct quote. If C<commands_quote> is |
360 | a space, no quoting will take place. |
361 | |

363 | if it starts and ends with the same quote character: leave it as it is |
364 | |
365 | if it contains no whitespace: leave it as it is |
366 | |
367 | if it contains whitespace, then |
368 | |
369 | if it contains quotes: better leave it as it is |
