Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

  * (ie, box filtering), we can save some work in color conversion by
  * calculating all the output pixels corresponding to a pair of chroma
  * samples at one time.  In the conversion equations
- *	R = Y           + K1 * Cr
- *	G = Y + K2 * Cb + K3 * Cr
- *	B = Y + K4 * Cb
+ *      R = Y           + K1 * Cr
+ *      G = Y + K2 * Cb + K3 * Cr
+ *      B = Y + K4 * Cb
  * only the Y term varies among the group of pixels corresponding to a pair
  * of chroma samples, so the rest of the terms can be calculated just once.
  * At typical sampling ratios, this eliminates half or three-quarters of the
  * multiplications needed for color conversion.
  *
  * This file currently provides implementations for the following cases:
- *	YCbCr => RGB color conversion only.
- *	Sampling ratios of 2h1v or 2h2v.
- *	No scaling needed at upsample time.
- *	Corner-aligned (non-CCIR601) sampling alignment.

+ *      Corner-aligned (non-CCIR601) sampling alignment.
  * Other special cases could be added, but in most applications these are
  * the only common cases.  (For uncommon cases we fall back on the more
  * general code in jdsample.c and jdcolor.c.)
