- minor simplification of #if/#endif handling ENH: improve input robustness with negative-prefixed expansions (#2095) - especially in blockMeshDict it is useful to negate an value directly. Eg, ``` xmax 100; xmin -$xmax; ``` However, this fails since the dictionary expansion is a two-step process of tokenization followed by expansion. After the expansion the given input would now be the following: ``` xmax 100; xmin - 100; ``` and retrieving a scalar value for 'xmin' fails. Counteract this by being more generous on tokenized input when attempting to retrieve a label or scalar value. If a '-' is found where a number is expected, use it to negate the subsequent value. The previous solution was to invoke an 'eval': ``` xmax 100; xmin #eval{-$xmax}; ``` which adds additional clutter.
